Mid-cap Stocks with Open Questions: 3 Stocks to Avoid

Mid-cap stocks like Amkor (AMKR), Waters Corporation (WAT), and Citizens Financial Group (CFG) may face intense competition and disruption. Amkor's high input costs result in a low gross margin, while Waters' organic revenue growth has fallen short of benchmarks. Citizens Financial Group's waning returns on capital imply its previous profit engines are losing steam. These stocks have a valuation ratio of 29.3x and 21.2x forward P/E, respectively.
